table 显示问题：- (id)initWithFrame:(CGRect)frame 中创建table 然后不显示

- (id)initWithFrame:(CGRect)frame

{

    self = [super initWithFrame:frame];

    if (self) {

        // Initialization code

        

    [self createTable];   // 出现显示问题， 放在 drawRect 中显示是正常的

       

    }

    return self;

}

// Only override drawRect: if you perform custom drawing.

// An empty implementation adversely affects performance during animation.

- (void)drawRect:(CGRect)rect

{

    // Drawing code

    

    

}

-(void) createTable

{

    

    mTable = [[UITableView alloc] initWithFrame:self.bounds style:UITableViewStylePlain];

    

    mTable.dataSource = self;

    

    mTable.delegate = self;

    

    [self addSubview:mTable];

    

    

    

    

}
